I believe this will do what you are looking for. I did a little testing and it seemed to work well:
ip prefix-list classful seq 5 permit 0.0.0.0/1 ge 8 le 8 ip prefix-list classful seq 10 permit 128.0.0.0/2 ge 16 le 16 ip prefix-list classful seq 15 permit 192.0.0.0/3 ge 24 le 24 Hope that helps, Rob.
